You might look at ip port forwarding.
//http://www.ox.compsoc.org.uk/~steve/portforwarding.html
You can nominate a single machine internally to handle a particular
TCP/IP port
eg 25 for SMTP (incoming mail).
This means you can set-up one of each type of server (WWW, ftp
etc) internally.
If you just want to login, you can telnet to the host with the Internet
IP address, and then use rlogin from there. Not much use with Windows
though. Presumably your ISP will dial your system when you try to access
your IP number? If not it will only work if your system has already
connected to the Internet.

I take it you have tried a Telnet client on the Windows box.....and it
didn't work ? You have no problem pinging from the windows machine to the
Linux machine ?
Then edit hosts.allow (?) in /etc. on the Linux box to allow your windows
box entry......remember no "root" logins from Telnet allowed unless you
reconfigure it to allow....(not recommended..)

Subject: Routing and kernel 2.2.x
Date: Sat, 22 May 1999 16:43:49 +0100
Hi all
I'm a bit confused with all this routing stuff and masquerading.
The fact is that I have a two linux boxes linked to a local network
in my Faculty. One is a standalone workstation, but the other has
a second ethernet card and is serving a small intranet through
IPmasquerading. Both are working fine, but lately I found some
differences
in the routing tables since I've upgraded to kernel 2.2.x.
Their routing tables show
a) Standalone machine
Destination Gateway Genmask Flags Metric Ref Use
Iface
localnet * 255.255.255.0 U 0 0 0
eth0
b) Server machine
Destination Gateway Genmask Flags Metric Ref Use
Iface
intranet * 255.255.255.0 U 0 0 0
eth0
localnet * 255.255.255.0 U 0 0 0
eth1
Neither of them has a default gateway. We do have a gateway at the
faculty's network
(let's call it facgateway) and I was used to set it up in the rc.d
scripts. The same
applies to the other entries in the routing table. Now I know that
kernel 2.2.x does
this automatically but I guess that the default gw entry should be set
manually, as
is the loopbak interface entry (which is also missing from the routing
table).
My question is: should I set up the default gateway and loopback with
the commands
#route add -net 127.0.0.0 netmask 255.0.0.0 lo
#route add default gw facgateway netmask 255.255.255.0 metric 1
I'm asking because everything seems to be working but I'm afraid of
being overloading
the network (or the server) because there is no default gateway. If I do
this the
routing table looks like
a) Standalone
Destination Gateway Genmask Flags Metric Ref Use
Iface
default facgateway 255.255.255.0 UG 1 0 0 eth0
localnet * 255.255.255.0 U 0 0 0
eth0
loopback * 255.0.0.0 U 0 0 0
lo
b) Server
Destination Gateway Genmask Flags Metric Ref Use
Iface
default facgateway 255.255.255.0 UG 1 0 0 eth1
intranet * 255.255.255.0 U 0 0 0
eth0
localnet * 255.255.255.0 U 0 0 0
eth1
loopback * 255.0.0.0 U 0 0 0
lo
Is this OK? Can one explain me why it does work both ways? Is the entry
localnet
(eth1) necessary? (the kernel sets it up automatically, so I guess it
is...)
Thanks in advance

Kernel 2.1 and 2.2 require ipchains over ipfwadm. Make sure you have the
package installed. Modify your /etc/rc.local as follows:
ipchains -a input -p tcp -j DENY --destination-port 137:139 -i eth0
ipchains -a input -p udp -j DENY --destination-port 137:139 -i eth0
ipchains -a output -p tcp -j DENY --destination-port 137:139 -i eth0
ipchains -a output -p udp -j DENY --destination-port 137:139 -i eth0

Date: Mon, 24 May 1999 14:14:18 +0100
Hi
We've been using an old i486-Sx/33 running kernel 2.0.30 with masquerading
as our internet gateway/firewall for about 2 years. The ISDN card is a
TELES-16.3 (non-PNP) and the connection to the local exchange is ISDN-2e.
I have just had ISDN HomeHighway installed at home and as I had a near
identical system to the office configuration lying around I presssed this
into service. However, the home system (which has a direct copy of the
office software) indicates that it is dialing the ISP but then isdn_net
causes a local hangup anything from 1 to 8 seconds later. As a test, I
substituted the cloned system for the working system in the office, and all
worked perfectly.
Is there a fundamental difference between ISDN-2e & HomeHighway which
requires the card, driver and/or isdnctrl to be configured differntly?

You can embed AT commands to set the speed in your chat script data file,
under RH
/etc/sysconfig/network-scripts/chat-ppp0
This is mine (with accounts stuff changed of course).
'REPORT' 'CONNECT'
'ABORT' 'BUSY'
'ABORT' 'ERROR'
'ABORT' 'NO CARRIER'
'ABORT' 'NO DIALTONE'
'ABORT' 'Invalid Login'
'ABORT' 'Login incorrect'
'' 'ATZ'
'OK' 'AT+MS=12,1,300,41333' <--- this line sets the rate to 41333
bps
'OK' 'ATDT555-5555'
'CONNECT' ''
'ogin:' 'name'
'ord:' 'passwd'
'TIMEOUT' '5'
'~--' ''
The maximum rate is probably more a result of line noise between your home
and the ISP.

I've actually measured downloads (simple stuff like ncftp, that shows

cable modems are cheaper, usually. but with the $49 pachell service,
they're clearly trying to force out any competition. and that $49 is
for a STATIC ip. most cable shops give out dhcp addresses, I believe.
cable modems are also more sensitive to noise and shared use. and
when they add new subscribers, the noise figures change so they have
to rebalance the circuits. not so with dsl.
(discl: I work for a cable modem company- and in my locale at least,
its better to get dsl than cable modems. ymmv, of course. and when
doscis 1.2 finally is out and working/stable, things may be totally
different and cable modems may actually be the mode of choice.)

Looks like your provider is blocking port 80 to force use of a proxy.
Just a remark: Reinstalling does not work on linux boxes. You find the
source of a problem reding log or (rare) reading source code.

Looks like your box remembers the dynIP it gets. If you connect to the
same provider twice and get a different IP, does the problem occur?
When is your masquerading set up? Is it an init script or does ip-up
script do it. Does the problem occur if you call ipfwadm to flush all
settings bettween to dialups?
>Is something wrong with my configurations or do I need a new ISP?
Didn't see any of your configurations.

Suse (at least 5.2 or higher) is rpm based. So you could try rpm for

If you want to run that many nodes on pc hardware availability will be
a problem. How does beowulf handle this? If you have 300 nodes and the

No online acces at the moment.
Is your router your dhcp server? Maybe your firewall script is
filtering the broadcasts which are needed to set up the IP adress and
which cant have valid IP adresses from the local net.
Turn on logging for denied/rejected packages on ports 67/68.
